a thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaterswas designed as a continuous-flow, completely-mixed homogeneous system. the reactor was operated at ten different organic loading rates ranging from 0.84 g cod/l·d to 7.00 g cod/l·d for a duration of approximately 250 days. the fundamental way to maintain optimum operating conditions of anaerobic digestio...

Additive manufacturing (AM), also known as 3D printing, constructs a 3D object in a layer by layer fashion. Comparing to traditional manufacturing technologies, it can build objects with complex individualized features with little extra effort. This characteristic endows additive manufacturing with the potential to realize mass customization. Continuous Liquid Interface Production (CLIP), a new...

In this paper an object-oriented representation of a continuous process plant is viewed as a directed multi-graph-based pictorial model. The associated modelling language has two components, the "rst describing the structure of production system in a pictorial manner and the second de"ning its behaviour. The structural}functional description realized through this language supports a signi"cant ...

To achieve a higher succinic acid productivity and evaluate the industrial applicability, this study used Mannheimia succiniciproducens LPK7 (knock-out: lahA, pflB, pta-ackA), which was recently designed to enhance the productivity of succinic acid and reduce by-product secretion. Anaerobic continuous fermentation of Mannheimia succiniciproducens LPK7 was carried out at different glucose feed c...

A flowsheet model for a continuous direct compression tableting process is developed and applied to process data. The model contains powder feeding, blending and tablet compaction unit operations. The dataset was provided by Merck & Co., Inc., Kenilworth, NJ USA using a GEA ConsiGma continuous direct compression process designed for a 50 kg/h throughput using a six ingredient, potentially comme...

If organizations wish to achieve continuous quality improvement they need to use appropriate selection of quality tools and techniques. In this paper a review of possibilities of the systematic use of seven basic quality tools (7QC tools) is presented. It is shown that 7QC tools can be used in all process phases, from the beginning of a product development up to management of a production proce...

In this paper, we present a new and innovative sheet material folding technology and the associated advances in folding different patterns using continuous manufacturing techniques. A novel approach is developed for the continuous folding process where sheet material is progressively folded in two dimensions, through a set of rollers, followed by a configured roller for the final folding in the...

Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...
